Title: Apparatus for recording compressed digital information to an optical disc
Inventor: MAEDA YASUAKI
IPC: G11B11/105
Filed: 1991-08-23
Abstract: The appts. records on an optical disc (2) having a memory (14) for storing input digital data compressed from a continuous signal. A signal encoder (15) arranges data from memory (14). The arrangement is multiple clusters at an interval of a set number of sectors annexing to each a linking sector. The cluster data is interleaved for the recording circuit (3, 4). An abnormality detection circuit (30) acts through a controller (7) to inhibit recording upon detection of abnormality. This performs a read out control of the memory.

Title: Integral beverage stirrer
Inventor: SINAVE JEAN-LUC J M
IPC: B01F27/91
Filed: 1991-11-06
Abstract: A integral beverage stirrer which incorporates the pitcher and a hand driven geared stirrer assembly in which the geared mechanism is mounted inside the lid of the pitcher.     ABSTRACT      In a beverage pitcher and stirrer, it has been proposed to provide a internal direct drive stirrer device to mix directly into the pitcher any beverage.  In this invention the stirrer device is a integral stirrer assembly, hand driven through a geared mechanism of two gear wheels mounted and being part and parcel of the lid.  The stirrer assembly is composed of the gear wheel mechanism, the rotating shaft and the mixing element.  The geared mechanism is composed of a small gear wheel, interlocked with the top end of the shaft, and of a larger internal gear wheel attached to the lid.  The rotating shaft is supported at the bottom center of the pitcher and is driven by the gear wheel mechanism incorporated in the lid.  The mixing element is a multiple blade screw type propeller attached to the bottom section of the rotating shaft.  Additionally the outside body of the internal gear wheel is used to hand drive the stirrer assembly and the lid is particularly designed to totally enclose the gear wheel mechanism.  When the handle is activated, the rotating motion transmitted by the gear wheel mechanism is increased approximately six times and is transmitted by the shaft to the mixing element.

Title: Helicopter virtual image display system incorporating structural outlines
Inventor: HAMILTON BRUCE E
IPC: G09B9/30
Filed: 1992-01-30
Abstract: A virtual image display system provides video displays based upon virtual images of the external world having synchronized structural outlines superimposed on the video displays to a pilot operating an aircraft such as a helicopter in non-visual flight conditions.  The virtual image display system includes a virtual imaging subsystem for generating virtual images of the external world, a video display subsystem for generating video images based upon the virtual images and for displaying the video images for the pilot's viewing, a sensing means for providing signals corresponding to the spatial location and perspective of the video display subsystem, a map comprising structural outlines corresponding to structural members forming the canopy structure of the helicopter, and a computer subsystem providing electronic interfacing between the elements of the virtual image display system, for synchronizing the orientation of the virtual imaging subsystem with the video display subsystem, and for processing the virtual image signals to provide signals to the video display subsystem to generate video displays.  The computer utilizes the helmet position signals to define the relative position and orientation of the video display subsystem in the cockpit, and utilizes such definition to reconstruct structural outlines from the map that are synchronized to the perspective of the video images.  The synchronized structural images are superimposed upon the video display.

Title: Knee brace having freecentric locking hinge
Inventor: FRANCE E PAUL
IPC: A61F5/01
Filed: 1991-05-31
Abstract: The present invention relates to a knee brace (10) which includes an upper and lower cuff (11, 12) which are attached at the medial and lateral sides of the knee joint by freecentric locking hinges. The freecentric hinge includes a free floating center of rotation which allows simultaneous translation and rotation of the upper hinge arm (13) relative to the lower hinge arm (14). The freecentric hinge may further include a locking mechanism which comprises a pin (23) located on the upper hinge arm (13) and a hook (26) located on the lower hinge arm (14) which may be forced into engagement to prevent further rotation of the hinge when it is desired to prevent hyperextension of the user's knee. A pair of tension straps (18, 19) may be attached across the back of the user's knee from the upper cuff (11) to the lower cuff (12), and adjusted in their length so that extension of the knee tends to generate tension in the straps (18, 19) which aids in pulling the upper and lower cuff members (11, 12) towards each other. The motion of the upper and lower cuffs (11, 12) towards each other causes the hook (26) and pin (23) of the locking mechanism to be correctly positioned for interengagement and locking of the hinge against further extensional rotation. If desired, the upper hinge arm (13) may be attached to the upper cuff (11) in a manner which allows free sliding movement therebetween in order to compensate for forces incident on the brace (10) due to the motion of the hinge as it tracks the rotation of the user's knee.
